Diagnosis

The female of S. inexpectatus sp. nov. can be separated from other species of this group by the combination of the following characters: supraclypeal area and clypeus very sparsely and finely punctate, strongly reticulate and matt ( Fig. 10 C–D), scutum densely and coarsely punctate ( Fig. 10 E–F), stigma brown, apical margins of metasomal terga black ( Fig. 10B ). The male is unknown.

Etymology

The discovery of such an unusual species was unexpected, which is reflected in its name.

Antenna dorsally blackish-brown, ventrally yellowish-brown.

MESOSOMA. Integument black. Mesoscutal disc between punctures densely reticulate and matt; disc densely (i = 0.5–1.0 d) and finely punctate ( Fig. 10 E–F). Metanotum about 2/3 as long as basal area of propodeum, apically with narrow carinate depression ( Fig. 10F ). Propodeum basally finely carinate ( Fig. 10F ).

Prepygidial and pygidial fimbriae blackish-brown. T1 densely (i = 1 d) but very finely punctate, apically a bit coarser, between punctures superficially sculptured and slightly matt; on following terga punctation slightly larger and stronger sculpture; T2–T4 with superficially sculptured and shiny, narrow apical tergal depression ( Fig. 10B ).
